'NITED STATES PATENT OFFICE.

DANIEL NEFF, OF AMSTERDAM, NEW YORK.

IMPROVED ROAD-SCRAPER.

Specification forming part of Letters Patent No. 84,570, dated December1, 1868.

To whom t may concern:

Be it known that I, DANIEL N FFF, of Amsterdam, in the county ofMontgomery, State of New York, have invented a new and useful machinefor scraping and leveling towingpaths to canals, highways, streets,embankments, and lands generally; and I do declare that the following isa full, clear, and exact description of the construction and operationof the same, reference being had to the annexed drawings, making' a partof this specification.

Figure l is a sectional view of the reach hereinafter referred to. Fig.2 is a view of such reach with sections connected together. Fig. 3 is aview of the metal clasp with which I cover the joint between the firstand center sections when coupled together. Fig. 4 is a view of myinvention arranged together in all its parts relatively, complete.

The nature of my invention consists in the following, viz: I firstconstruct an axle and two wheels, one at each end, which wheels haveflanged tires or rims, as shown in Fig. 4 by a a a a, to the center ofwhich axle I attach a shaft or reach, represented in Fig. 2 by b b, bymeans of an iron or other metal staple and bolt, or two counter-staples,which connections give a free and easy motion to the reach. The otherend of this reach is fastened to the ccnter top of the scraperhereinafter described, which scraper is represented, showing point wherereach is attached, in Fig. 4, by c c c.

The reach A A, Fig. 2, is constructed in three parts, as shown in Fig.l, by B i, B, B a, of wood or metal, and of any required length. In thecenter-piece, Fig. l, of such reach I embed a short swiveled metal bolthorizontally, and so constructed and connected by and with the other twosections of the reach B t', B, B a, Fig. l, as to give a lateral andperpendicular motion to section B a, Fig. l, of the reach, while sectionB i, Fig. l, attached to the axle, remains immovable. I sometimesconstruct this reach with the swiveled bolt passing through and turningat its connection with and at the axle instead of having the turningmotion in the center of the reach.

I construct the scraper c c c with the upper part of wood, about ve feetin length, and

from one to two feet in width or height, while the lower side, d d d,Fig. 4, is shod with or made of metal, securely fastened to the woodenframe c c c and sharpened or beveled upon the lower edge. From the upperpart of this scraper I construct two bent guides or handles, for theconvenience of the operator, as represented by f f, Fig. 4. The frontside of this scraper-board d d d c c c is dished or V-shaped. From thefront of this scraper I construct parallel selnicircles i t' i, Fig. 4,leaving a sufficient space between them for the reach A A to move freelythrough. Through the surface of these parallel selnicircles I pierceholes, through which an iron bolt passes, going through theabovedescribed reach in its passage, which bolt and seniicircles areused for the purpose of keeping the scraper at any required angle withrespect to the surface over which it moves, while the propelling powerdirects or leads in a horizontal course.

The swiveled metal bolt embedded horizontally in the center of the reachA A permits the blade or edge of the scraper d d d, resting on theground, to conform its motion and position, without the aid of theoperator therefor, to the 4form of the surface over which it is moving,without any regard to the position of the carriage or axle by which thescraper is drawn.

The advantage gained by this invention is that a scraper constructed asherein described, and represented in Fig. 4, will, by the aid of oneteam and one man, perform in one day as much labor of the kind for whichit is intended as one hundred men with hoes and shovels could do in thesame time, and this machine will scrape and level the ground better thanany other device of the kind known.

What I claim, and desire to secure Letters Patent for, as my invention,is-

The self-adjusting reach having a swiveled metal bolt embeddedhorizontally therein, to be used as a connection for and in combinationwith a scraper, d d d, and carriage a a a a, constructed substantiallythe same as described in the foregoing specification.
